What is Supination?
The Mechanics of Outward Rolling
Supination (or underpronation) occurs when the weight rolls onto the outer edges of your feet. This is typically caused by having High Arches (Pes Cavus), which are rigid and lack natural shock absorption.
Because the foot doesn't roll inward enough to absorb impact, the shock is transmitted directly up the leg to the knees, hips, and back. This misalignment also puts you at high risk for ankle inversion sprains.
Common Symptoms:
- Wear patterns on the outer edge of your shoes.
- Frequent ankle sprains or feeling of instability.
- Pain on the outside of the shin (shin splints) or knee (IT Band).
- Calluses on the outer edge of the foot.
Why Orthotics Are The Primary Treatment
The goal of treatment is Stability and Shock Absorption.
Custom orthotics use a lateral wedge (posting) to gently tilt the foot inward to a neutral position. They also fill the high arch cavity to increase the contact area, distributing pressure evenly and providing the shock absorption your foot lacks naturally.
Fast Facts
- Risk: High risk of stress fractures due to poor shock absorption.
- Instability: Major cause of chronic ankle sprains.
- Correction: Lateral support devices are 92% effective.

Take Your QuizEffective Treatment Hierarchy
Medical consensus focuses on two goals for Supination: Shock Absorption & Lateral Stability. You must cushion the impact and prevent the ankle from rolling outward.
1. Cushioned Shoes
Neutral Footwear
Highly cushioned "Neutral" shoes help absorb some of the shock that high arches miss. While helpful for comfort, shoes alone cannot fill the arch cavity to redistribute pressure effectively.
2. Bracing & PT
Ankle Support
Physical therapy strengthens the peroneal muscles to fight the outward roll. Ankle braces are used for chronic instability but restrict natural motion and can weaken the ankle over time.
3. Custom Orthotics
Lateral Stability
The medical standard. Custom orthotics use lateral posting to tilt the foot inward to neutral and a high arch fill to distribute weight evenly across the entire foot, preventing sprains.

Why Store-Bought Insoles Often Fail Supination
Understanding the difference between simply cushioning the foot versus mechanically preventing outward rolling is key to long-term relief.
Generic Insoles
mass produced
-
Lacks Lateral Support
Generic insoles are designed for the masses and lack the specific lateral wedge needed to stop outward rolling.
-
Poor Shock Absorption
Rigid, supinated feet need deep shock absorption, but standard foam compresses too quickly.
-
One-Size Arch
Pre-made arches are often too low for high-arched supinators, leaving a gap where support is needed most.
